• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky nang xa hoi. hieu va phan luc va tinh bai ((cua tre) OR (((cuu tre) OR (cau treo)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky nang xa hoi. hieu va phan luc va tinh bai ((cua tre) or (((cuu tre) OR (cau treo))))".
